Patented Jan. 13, 1948 STATES PATENT OFFICE VERTICALLY ADJUSTABLE GRAIN LOADING SCREW The present invention relates to new and useful improvements in grain loading machines, and has for its primary object to provide, in a manner as hereinafter set forth, a portable apparatus of this character which is particularly adapted to fill bins, tanks, cars, et cetera.

Another very important object of the invention is to provide a grain loading machine of the aforementioned character which may be expeditiously usted to operate at different heights.

Other objects of the invention are to provide grain loading machine of the character described which will be comparatively simple in construction, strong, durable, highly efiicient and reliable in use, compact, and which may be manufactured at 10W cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawing wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure 1 is a top plan view of a grain loading machine constructed in accordance with the present invention.

Figure 2 is a view in side elevation of the machine.

Figure 3 is a view in vertical longitudinal section, taken substantially on the line 3-3 of Figure 1.

Figure 4 is a cross sectional View, taken substantially on the line 4-4 of Figure 2.

Figure 5 is an end elevational view of the conveyor, showing the drive therefor.

Figure 6 is a cross sectional view, taken substantially on the line fi-6 of Figure 1.

Figure 7 is a detail view in vertical section through the transmission which drives the conveyor.

Referring now to the drawing in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a movable base I. Mounted on the forward portion of the base l is a platform 2. A suitable engine 3 is mounted on the platform 2.

Rising from the rear portion of the base I is a pair of standards 4. A substantially U-shaped hanger 5 is suspended between the standards 4 for swinging movement in a vertical plane. The rear end portion of a frame structure 5 is fixed on one side portion of the hanger 5. The frame structure 6 includes a pair of spaced, parallel bars 1 of angle iron which are connected by cross members 8.

The forward end portion of the frame structure 6 is supported for vertical swinging adjustment by means including legs 9 which are pivotally mounted, as at Ill, on the platform 2 for swinging movement in a vertical plane. Pivotally mounted on the upper end portions of the legs 9 is a pair of substantially channel-shaped slides II which are operable on the bars I. Chains l2 have one end connected to the legs 9 and their other end portions adjustably connect, as at l3, to the platform 2 for supporting said legs in adjusted position.

The frame structure 6 carries a conveyor M. The conveyor l4 comprises a tube l5 of suitable length and diameter which is mounted between the bars I. An auger 16 (see Fig. 3) is operable in the tube l5. The shaft ll of the auger I6 is journaled in suitable bearings l8. Rising from the rear end portion of the conveyor tube 15 is a hopper 19. A discharge spout 20 projects downwardly from the forward end portion of the tube l5.

Also mounted on the hanger 5 is a transmission 2 I. Projecting laterally from the transmission 2| is a shaft 22. The shaft 22 is driven from the engine 3 by a belt and pulley connection 23. Also projecting from the transmission 2i is a driven shaft 24. The shaft 24 drives the shaft ll of the auger I6 through a chain and sprocket connection 25. Beveled gears 26 (see Fig. '7) in the transmission 2| operatively connect the shaft 22 to the shaft 24.

It is thought that the operation of the machine will be readily apparent from a consideration of the foregoing. Briefly, the apparatus is moved to the desired location and the forward end of the conveyor [4 is swung upwardly to the necessary elevation. Of course, the conveyor I4 swings with the hanger 5 on the standards 4. When this occurs, the legs 9 swing upwardly, the slides ll traveling longitudinally on the bars I of the frame structure 6. The chains l2 are then secured at [3 for holding the conveyor [4 in adjusted position. The engine 3 is then started for driving the auger 16 of the conveyor l4. Of course, the grain or other material to be elevated is placed in the hopper l9 through which it flows into the lower portion of the tube I5 to be moved upwardly by the auger IE to the discharge spout 20.

It is believed that the many advantages of a grain loading machine constructed in accordance with the present invention will be readily understood, and although a preferred embodiment of the apparatus is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:

1. A grain loading machine comprising a base, 5 a pair of standards rising from the base, a. substantiall U-shaped hanger suspended between the standards for swinging movement in a vertical plane, a frame structure fixed on the hanger, a conveyor mounted on the frame structure, said conveyor including a tube and an auger operable in thetube, said auger comprising a shaft, a transmission mounted on the hanger, a power plant mounted on the base and having operative connection with the transmission, means operatively connecting said transmission to the shaft of the auger, and means on the base for adjustably supporting the conveyor in an inclined position.

2. A grain loading machine, comprising a base, a pair of standards rising from the base, a substantially U-shaped hanger suspended between the standards for swinging movement in a vertical plane, a frame structure on the hanger, a conveyor mounted on the frame structure, said conveyor including a tube and an auger operable in the tube, said auger comprising a shaft, a transmission mounted on the hanger, a power plant mounted on the base, a drive-shaft extending from said transmission, means operatively connecting said drive-shaft to the shaft of said auger, a drive-belt operatively connecting said power plant to said transmission, and means on the base for adjustably supporting the conveyor in an inclined position.

3. The device as defined in claim 2, in which said means for supporting said conveyor comprises in combination, parallel angle bars defining said frame structure, legs pivotally mounted on said base for swinging movement in a vertical plane, channel-shaped slides pivotally mounted on said legs and operable on said bars, and longitudinally adjustable chains connecting the midportions of said legs to said base, all for the purpose set forth.
